在物理处理法中应用最多的是吸附法
吸附法：在物理处理法中应用最多的是吸附法，这种方法是将活性炭、粘土等多孔物质的粉末或颗粒与废水混合，或让废水通过由其颗粒状物组成的滤床，使废水中的污染物质被吸附在多孔物质表面上或被过滤除去的方法。活性炭的吸附率、BOD去除率、COD去除率分别达93%、92%和63%。
Adsorption method: Adsorption method is the most widely used method in physical treatment. This method is to mix the powder or granule of porous substances such as activated carbon and clay with wastewater, or let wastewater pass through a filter bed composed of its granules, so that the pollutants in wastewater are adsorbed on the surface of porous substances or filtered out. The adsorption rate, BOD removal rate and COD removal rate of activated carbon were 93%, 92% and 63%, respectively.
